一、前言煤矿所使用的炸药是经过安全性能检验合格的炸药。如炸药正常反应,爆破正常进行时是非常安全可靠的,很难成为引燃瓦斯和煤尘的点火源。但是,在实际的爆破中,由于各种各样的原因阻碍了正常的爆破,异常爆破和炸药的爆轰反映中断所产生的残留炸药等现象是发生爆破灾害的主要原因。煤矿发生的异常爆破有空爆、龟裂爆
I. Preface The explosives used in coal mines are explosives that have passed the test of safety performance. Such as explosives normal reaction, normal blasting is very safe and reliable, it is difficult to ignite gas and coal dust ignition source. However, in actual blasting, normal blasting is hindered by various reasons, and abnormal blasting and detonation of explosives reflect the residual explosives generated by the interruption, which are the main causes of blasting disasters. Unusual explosions in the coal mines are available, cracked and exploded
